دور حلقات الجودة في تشخيص العيوب و أثرها على جودة المنتج : دراسة حالة على مصنع إنتاج سيارات الصالون

Abstract EN

Increasing customer satisfaction and obtaining a greater share in the market and achieving profitability requires eliminating the conflict between quality and low cost and delivering on time, and it is to prevent errors or defects in outputs, and this is what the globalization of markets and economic openness have imposed.

Thus, the current study aims to strengthen the theoretical framework of the quality circles technology and the integrated assessment of each of the defects and their costs through the use of one of the quality loops tools represented by checklists to detect defects and know their causes, as well as determine the relationship between the defects of the independent variable and the repair costs of the dependent variable.

Eviwes to analyze the effect of special results of safety defects, stopping, performance and appearance on repair costs, and the approach to complete the research.

Case study methodology, choosing a good production line as an area of study - Saloon car production plant.

The research found that the most influential reason for the low level of product quality and the consequent high costs of internal failure represented by the costs of repair is an increase in costs due to labor, as the percentage of workers' contribution to the occurrence of defects reached 50% of the total defects, as for work methods and product components And the body, machinery and equipment, their contribution amounted to 25% , 22% , and 3% , respectively.

The results of the integration test also confirmed that there is no long-term equilibrium relationship between defects and repair costs, and this requires that the product is not accepted with any degree of deficiency.
